Plastisol is a suspension of PVC or other polymer particles in a liquid plasticizer; it flows as a liquid and can be poured into a heated mold. Aside from molding, plastisol is commonly used as a textile ink for screen-printing.
Plastisol is used as ink for screen-printing on to textiles. Plastisols are the most commonly used inks for printing designs on to garments, and are particularly useful for printing opaque graphics on dark fabrics.
Plastisol inks will not dry on their own, but must be cured.
Plastisol tends to sit atop the fabric instead of soaking into the fibers, giving the print a raised, plasticized texture. Unfortunately, this method does not provide the best hands to the fabric. Other inks can produce a softer feel.
The next time someone asks you, "what is plastisol?", we hope you now have an answer for them.
